在为 Android 活动创建视图时显示进度对话框
在 Android 活动中，我在构建报告（视图）方面有一个漫长的过程。我想在创建视图时显示一个进度对话框“正在构建报告..请稍候”。是否可以启动活动（屏幕切换），然后显示进度对话框，然后呈现视图？
我想或者我可以在主活动的后台线程上构建视图，同时显示进度对话框，然后一旦创建视图，我就可以启动下一个活动并呈现构建的视图。
处理此类问题的最佳方法是什么，即在构建复杂视图时显示反馈？视图必须用代码构建，而不是 XML，并且随着数据的迭代，它可能需要几秒钟。我希望应用程序看起来响应迅速。
谢谢。
In an android activity I have a lenghty process in building a report (view). I would like to show a progress dialog "Building Report..Please Wait" while the view is being created. Is it possible to start and activity (screen switch) and then show a progress dialog and then present the view?
I guess alternatively I could build the view on a background thread from the main activity while showing a progress dialog and then once the view is created I could start the next activity and present the built view.
What is the best way to handle something like this, i.e. show feedback while a complex view is being built? The view has to be built in code, not XML, and with the iterations of the data it can be a few seconds. I want the application to appear responsive.
Thank you.

我明白了这一点。我显示进度对话框，然后启动一个后台任务，该任务在 RunOnUiThread 元素中具有 setcontentView 并隐藏进度对话框。
I figured this out. I show the progress dialog and then start a background task which has the setcontentView in the RunOnUiThread element and hide the progress dialog.
